I would love Stack Overflow to recommend questions for me to answer, based on questions I have answered in the past (perhaps taking into account how many upvotes my answer received).

I find the tagging system too general for finding questions to answer. For example, questions tagged ravendb cover a wide range of topics, many of which are out of my comfort zone, but I would probably be inclined to answer a question that is specifically about writing an extension for RavenDB.

I imagine the term vector of a previously answered question could be compared with new questions to yield a set of sensible recommendations.

The more you participate on the site, the more information Stack Overflow has on the questions that you're interested in. Sure, you can go to all the effort of defining a list of "interesting" tags - but even if you don't, SO will do it for you - simply visiting questions with the same tag will cause the site to infer your interest in them.

On top of that, asking or answering questions builds a list of tags you're active in in your profile. These are used by the Unanswered Questions page to determine which questions you might be well-suited to answer.

Now, there's always a chance that the tagging system doesn't adequately reflect your specific interests. Some of this is unavoidable - tags can't be infinitely granular... But in cases where you encounter a poorly-tagged question, take that opportunity to re-tag it, and thereby help the system - and other users - better find questions of interest.

Garr, I hate the I-know-what-stuff-you-like feature. On Physics.SE it highlights all quantum mechanics questions--annoying since QM is my most O_0 topic. I've disabled it by choosing a nonexistant tag as my favorite :\

Well, just be thankful it doesn't identify arbitrary phrases in questions as your "favorites" somehow... (Not completely sure, but that might have been what Richard was suggesting)

that would be a nightmare. Not being an expert in anything, I usually give answers on varied topics. I can't even imagine what the system would assume I like :P
